title: The impact of mobile phone screen size on user comprehension of health information.
abstract: Within the field of mobile health, there is little research conducted on the impacts of mobile health technologies and applications on user comprehension of health content. In this study, we examine the difference between small, medium and large screen mobile phone that affect the user comprehension of health content. We designed an experimental study where 33 users read the contents of a health application on different mobile phone screen sizes. Each participant was timed, tracked for correctness, and gave ratings for both readability and satisfaction on each task. In addition, they were asked some questions about the contents. Results show that there was no significant impact of the screen size on user comprehension of the contents. However, it was found that participants with small screen size took longer to read the health contents.
